refers to the level of water in a well under normal, undisturbed, no-pumping conditions. Static water level is best determined when the well has not been pumped for several hours prior to measuring. You may get a false reading if the well was pumped just before the static water level is measured.
What is the difference between water level and water table?
Sometimes they mean the same, but not always. While the upper most level (top) of the saturated zone in an unconfined aquifer is the water table, the level of water seen in a well is commonly referred to as water level.
How do I measure the water level in my well?
Attach a sinker to the line, drop it down to the bottom of the well, and take up the slack. Using a permanent marker, mark the line at ground level. Reel in the line and measure the distance between the mark and the sinker. This is the well depth.
What is the dynamic water level?
5.1.1 Static water level ( SWL) : is the level at which water stands in a well. A measuring point should be specified for measurements. A negative value of SWL denotes a level below ground level. 5.1.2 Pumping Water Level ( PWL) Sometimes is refferred to also as dynamic water level (DWL).
What is pumping water level?
Drawdown: The drawdown in a well is the difference between the pumping water level and the static (non-pumping) water level. Drawdown begins when the pump is turned on and increases until the well reaches “steady state” sometime later.
Is the water table flat?
Sediment or rocks that are full of water are saturated. The water table sits on top of what experts call the zone of saturation, or phreatic zone. The area above the water table is called the vadose zone. Unlike the tables you’d find in your house, a water table usually isn’t flat, or horizontal.
